Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678730, here are decompositions:

17 + 8678713 = 8678730
23 + 8678707 = 8678730
29 + 8678701 = 8678730
31 + 8678699 = 8678730
37 + 8678693 = 8678730
59 + 8678671 = 8678730
61 + 8678669 = 8678730
127 + 8678603 = 8678730

Showing the first eight; more decompositions exist.
